Scientists Image an HIV Particle Being Born
FiReaNGeL alerts us to a huge development in virology and microscopy: by using a specialized microscope that only illuminates a cell's surface, scientists at Rockefeller University have watched, in real time, hundreds of thousands of molecules coming together in a living cell to form a single particle of HIV-1. A video is available on Rockefeller's front page. "By zeroing in at the cell's surface, the team became the first to document the time it takes for each HIV particle, or virion, to assemble: five to six minutes. 'At first, we had no idea whether it would take milliseconds or hours,' says Jouvenet. 'We just didn't know.' 'This is the first time anyone has seen a virus particle being born,' says Bieniasz, who is an associate professor and head of the Laboratory of Retrovirology at Rockefeller and a scientist at the Aaron Diamond AIDS Research Center. 'Not just HIV,' he clarifies, 'any virus.'" -

Improving Noise Analysis with the Sound of Silence
Roland Piquepaille writes "Researchers at Rockefeller University have built a mathematical method and written an algorithm based on the way our ears process sound that provides a better way to analyze noise than current methods. Not only is their algorithm faster and more accurate than previous ones used in speech recognition or in seismic analysis, it's also based on a very non-intuitive fact: they know what a sound was by knowing when there was no sound. 'In other words, their pictures were being determined not by where there was volume, but where there was silence.' The researchers think that their algorithm can be used in many applications and that it will soon give computers the same acuity as human ears. Read more for additional references and pictures about this algorithm." -
Protein Researchers Win Nobel Prize In Chemistry
nucal writes "The 2003 Nobel Prize in Chemistry was awarded to Rod MacKinnon and Peter Agree for their work on proteins that form ion and water channels in cell membranes. In particular, solving the structure of potassium channels was a major achievement, since this was the first multispan transmembrane protein structure to be solved by X-ray crystallography. There is also structural information on aquaporins (water channels) as well."
